Is G gigahertz or gigabytes? Assuming gigahertz, I'm not too sure how long it takes to bring a sequence to 100 digits on a P3, but this subproject is fine for slow but not too slow computers such as the earlier P4s. That's one of the good things about this project.

My suggestion would be to put no more than a quad on this sort of subproject for many days.
I personally run most sequences to 105-110 digits that i get from subprojects. I use subprojects to gain myself nice sequences and then run them high.
unreserving 804192 at 117 digits
edit: the database is being very slow at accepting my factors i will have the file available if needed
edit2: just noticed there are 5610667 things in the database's queue a lot!!

Done with these three, keeping one reserved:
821232 (c104) 781 - 4602 . 175296903.. = 2^3 <- keeping reserved
823620 (c102) 853 - 1262 . 363890264.. = 2^2 * 3 * 7^3
821640 (c106) 490 - 1106 . 271031219.. = 2^3 * 3 * 5^2

Yes, I was referring to GHz. Since that one machine seems to be running some of these sequences within a day, I've grabbed one of the subproject #4 sequences to see what it does. Although it is a 2.4 GHz, it only has 512M RAM. I have it running 24/7 with aliqueit at normal priority under WinXP.

It reached 103 but it takes too long to break a mid-c90 on my G4 Mac.
I can't get GGNFS compiled so I only use msieve.
Someone else can have fun with it.

Reserving 817242.

That someone will be me. I've put the reservation in here because it is likely to go below 100 again.
Haven't had a downdriver in ages so this will hopefully be fun.
